Travel visa
A travel visa (from Latin charta visa 'paper that has been seen'; also known as visa stamp) is a conditional authorization granted by a polity to a foreigner that allows them to enter, remain within, or leave its territory. Visas typically include limits on the duration of the foreigner's stay, areas within the country they may enter, the dates they may enter, the number of permitted visits, or if the individual can work in the country in question.
